Everywhere
Pakistan’s Gifts
Former Prime Minister (PM) of Pakistan, Imran Khan, 70, was found guilty and sentenced to three years in prison, in the ’Toshakhana’ case. And he has been barred from Politics for five years. The case is that Imran Khan misused his office, during his tenure as PM from 2018 to 2022, to buy and sell gifts in the State’s possession that were received during visits abroad and worth more than 140 million Pakistani rupees. Protocol requires PM’s to store all gifts in the State’s ‘safe house’, while Khan is accused of having sold them at a profit. The objects include watches, perfumes, diamond jewellery, and dinner sets. Imran Khan said he legally purchased the items.
He now sits in jail -on the bench- waiting for some magic decision by the Higher Courts where he has made a third-umpire kind of appeal. Meanwhile, Pakistan’s Parliament has been dissolved and the Elections are pitched ahead at a convenient distance.
Bangladesh’s Dengue Outbreak
Dengue, also called ‘break-bone fever’, is a mosquito-borne viral infection disease that is common in warm, tropical and subtropical regions of the World.
The dengue causing virus (DENV – single strand RNA of the Flaviviridae family) spreads to people through the bite of an infected Aedes species (Aegypti or Albopictus) female mosquito. Almost half of the world’s population live in areas with a risk of dengue and is often a leading cause of illness in these areas. These mosquitoes also spread Zika, Chikungunya, and other viruses.
Mosquitoes become carriers of the disease when they bite a person infected with the virus. Such infected mosquitoes can then spread the virus to other people. Bites from infected mosquitoes are the only mode of transmission. Infected mosquitoes continue to transmit the dengue virus with each blood meal for the rest of their lives.
But then, where did the Dengue Virus first come from?
Scientists hypothesise that the dengue viruses evolved in non-human primates and jumped from these primates to humans in Africa or Southeast Asia between 500 and 1000 years ago. They probably originated in monkeys and spilled over to humans.
Mosquitoes acquire the virus when they feed on a viraemic (virus present in the blood) host, after which the virus infects many tissues, in a susceptible species, including the salivary glands. The incubation period of the dengue virus is 3–14 days, with an average of 4–7 days. Humans are the main amplifying host of the virus. In tropical and sub-tropical urban areas, the viruses are maintained in a seemingly never-ending human-mosquito cycle.
Dengue is endemic in at least 100 countries in Asia. i.e., the infection is constantly present; and the disease occurs regularly in the community.
Mosquitoes typically lay eggs near stagnant water in containers that hold water, like buckets, bowls, animal dishes, flower pots, and vases, which serve as breeding grounds for further spread of mosquitoes bites, and the disease.
Symptoms of dengue include high fever, headache, rash, and muscle and joint pain. In severe cases there is serious bleeding and shock, which can be life-threatening and require hospital care. Treatment includes fluids and pain relievers.
Those who become infected with the virus a second time are significantly at a greater risk of developing a severe disease condition. A person can be infected with dengue multiple times in their life.
There is no treatment for the infection itself, but the symptoms that a patient experiences can be managed. There is no vaccine or drug that specifically treats dengue.
Now, over to Bangladesh where dengue is spreading like wild-fire.
Urbanisation, migration, and climatic changes are spurring a surge in dengue virus infections and Bangladesh is facing the effects. It registered record numbers of dengue cases and deaths amid an accelerating outbreak. The country has reported 61,500 cases of dengue so far in 2023, 85% of which date from July, as well as about 290 deaths. Reports have emerged of health-care facilities being overwhelmed. Moreover, although the risk of dengue is present throughout the year in Bangladesh infections typically peak in August and September.
The El-Nino phenomenon, which is associated with increased temperatures in Southeast Asia, started this year in June 2023. And has been linked to major dengue epidemics. A hot and wet climate is perfect for dengue. Countries like Cambodia, Malaysia, and Thailand are currently seeing a lot of transmission.
Dengue became established in Bangladesh sometime around the year 2000. Cases have historically been concentrated in the three largest cities: the capital Dhaka, Chittagong, and Khulna. Infection rates were far lower for people living outside urban areas. However, as Bangladeshis become increasingly mobile, they experienced a greater spread of dengue. People bring the mosquitoes back to their communities as well as the viruses that can be transmitted by the mosquitoes.
Dhaka has been particularly badly hit by the current outbreak. It is one of the most densely populated cities in the world and is rapidly growing. Dengue thrives in conditions of unplanned urbanisation.
Says a Professor in the Department of Zoology at Jahangirnagar University in Dhaka, “There is a water supply problem in Dhaka, so people keep water in buckets and plastic containers in their bathrooms or elsewhere in the home. Mosquitoes can live there all year round. Our waste management system is not well planned. Garbage piles up on the street; you see a lot of little plastic containers with pools of water in them. We also have multi-storey buildings with car parks in the basements. People wash their vehicles down there, which is ideal for the mosquitoes”.
Construction sites abound in Dhaka, with plenty of water lying around. Vector control is the responsibility of the city authorities who are doing their best with the spraying and fogging.
The Aedes Aegypti mosquito has now developed resistance to malathion, the insecticide used in Dhaka. The mosquito has already shown resistance to pyrethroid in Bangladesh. The use of mass spraying is not very convincing and there is not much evidence that removing breeding spots and applying insecticide reduces dengue. A mosquito bites during the day, which limits the effectiveness of bed-nets; it is excellent at hiding and needs little more than a thimble-full of standing water to proliferate. Once it is inside a residence, it is extremely difficult to eradicate.
With the evolution of the dengue virus, it does not cause critical symptoms in many instances. Because of this, people often ignore it, but the disease must be diagnosed early so that it can be treated before it gets complicated.
Perhaps the best hope for Bangladesh is a cost-effective vaccine. Presently, clinical trials are underway in a promising single-dose vaccine developed by the US National Institutes of Health (Bethesda, MD, USA) in collaboration with the University of Vermont Vaccine Testing Center (Burlington, VT, USA) and Johns Hopkins University (Baltimore, MD, USA). Bangladesh has immediate no plans to roll out either the Sanofi Pasteur dengue vaccine – made by French multinational company Sanofi – which is only recommended for individuals previously infected with dengue, or the newer product developed by Takeda – a Japanese Company.
And these mosquitoes have been around for ages!
Hawaii’s Wild-Fires
Hawaii is an island state of the United States (US) – one of the 50 States – about 3200 km from the US mainland, in the Pacific Ocean. It is the only US state outside North America, the only state that is an archipelago, and the only state in the tropics. Hawaii is known for its beautiful beaches, its laid-back lifestyle, and its delicious food.
The idyllic Hawaii is besieged by unprecedented, apocalyptic wildfires that are raging across Hawaii’s Big Island and Maui. Lahaina, the historic seaside town that was once the capital of the Kingdom of Hawaii has been largely reduced to ash. Lahaina being a touristic and economic hub of about 9,000 people, hundreds of families have been displaced. “We have no more Lahaina. It’s gone,” said a resident.
Over 60 people have died and hundreds of structures have been destroyed as fires continue to rage the island. This is the worst natural disaster in the history of Hawaii.
The fires first began this Tuesday, and have since grown and spread in destruction, forcing hundreds of evacuations and leaving thousands without power. Most of the fires on Maui – fuelled in part by violent winds from Hurricane Dora, churning more than 800 miles away – have not yet been contained. New brush fires also erupted on Hawaii Island as officials work to extinguish the ongoing deadly wildfires.
The exact cause of the fires is unknown, although some experts believe human development on the island is at least partly to blame; including non-native grass planted by plantation owners unfamiliar with the native ecosystem, which is dry and prone to fires.
A NASA Satellite imagery showed that dry conditions and strong winds helped fuel destructive wild-fires in Maui.
When a lush Hawaii, caressed by the sea, can turn into a hot-bed furnace, no spot in the World can be considered safe from the effects of Climate Change.
Moon Missions
Last weekend, India’s Chandrayaan-3 was successfully manoeuvred into the lunar orbit. Now the spacecraft is being gradually pulled into the gravity of the Moon with ‘regular, controlled orbit lowering manoeuvres’ by the Indian Space Research Organization (ISRO). A soft landing on the unexplored South Pole of the Moon is scheduled on 23rd August. ISRO is confident that the mission will be a success.
While India is slowly inching to the moon, this week Russia launched it’s first moon-landing spacecraft in 47 years. A Soyuz 2.1 rocket carrying the Luna-25 spacecraft blasted off from the Vostochny Cosmodrome, 5550 km East of Moscow, this Friday. The landed was boosted out of Earth’s orbit towards the Moon over an hour later and the Russian Space Agency Roscosmos is now commanding Luna-25. The lander is expected to touch down on the Moon’s South Pole, on 21st August. Russia’s stated goal is to land where no-one else has landed and to find water on the Moon.
India has company out there. And there is a brewing ‘soft competition’ – no country has made a soft landing on the South Pole of the Moon.
India’s Parliament
Perhaps for the first time in a very long time, people were suddenly watching speeches by Members of Parliament (MP) in India’s two Houses of Parliament – the lower, Lok Sabha and the upper, Rajya Sabha.
This season was perhaps one of the noisiest ever and bedlam all the way through. Even a final parting ‘Flying Kiss’ by a ‘recently re-installed MP’ failed to spill love and only generated uproar and more heat. India’s Dairy King, Amul, said it best in a cheeky, delicious advertisement, ‘Frying Kiss. Amul – Wins Everyone’s Confidence’
The Opposition, like a deer caught in the headlights, brought a ‘No Confidence Motion’ on the Government led by Prime Minister Narendra Modi, hoping to put the Government on the mat ahead of Parliament Elections in 2024. The focus was on the ethnic violence in the State of Manipur. However, it gave the Government a fabulous opportunity to talk about its achievements and instead wrestle down the Opposition to the mat. Plus, the Government had the numbers in Parliament.
The government easily defeated the no confidence motion after a fiery speech by the PM at the climax of a three-day debate.
The motion was defeated in a voice vote called by the speaker of the Lok Sabha shortly after opposition MPs staged a walk-out.
Women’s Football
Four-time World Cup winners United States of America were knocked-out by Sweden in penalties 5-4 following a goal-less play-time in the knock-out stage.
Colombia are through to the FIFA Women’s World Cup quarter-finals, the last Eight, for the first time, beating Jamaica 1-0.
The Quarter final line-up is: Spain versus (vs) Netherlands; Japan vs Sweden, Colombia vs England, and France vs Australia happening on 11th and 12th August.
Spain beat Netherlands 2-1, to advance to the semi-finals as did Sweden likewise beating Japan 2-1.
The race for the Golden Boot, has Japan’s Hinata Miyazawa at 5 Goals, France’s Kadidiatou Diani at 4 goals, and others with three or two goals, on the field.
Steps to Healthy Living
It’s generally believed that walking at least 10,000 steps per day is one of the best ways for maintaining an active lifestyle: enough to extend your life due to ‘good health’. This is in keeping with the fundamental truth of any physical activity: any movement is better than no movement at all.
Now it’s been found that walking just 4,000 steps per day may be enough to help extend your life, according to a new research review published in the European Journal of Preventive Cardiology. The researchers found that more movement is better, with each additional 1,000 steps per day associated with a roughly 15% lower risk of premature death. But research suggests that workouts don’t need to be all that gruelling or lengthy to improve your health. Everything from walking to housework to dancing can contribute to well-being, studies have shown.
